A home-built co-electrospinning apparatus was fabricated that was comprised of a high-voltage power supply, two concentric capillary needles, and one screw-type pump syringe. Eucalyptus-derived cellulose was dissolved in N-methylmorpholine oxide (NMMO) at 120 degrees C and diluted with dimethyl sulfoxide (DMSO) which was used in the external concentric capillary needle as the shell solution. A cellulose nanocrystal suspension obtained by the sulfuric acid hydrolysis of bleached sisal and cotton fibers was used as the core liquid in the internal concentric capillary needle. Three flow rate ratios between the shell and core, four flow rates for the shell dope solution, and four high voltages were tested. The resultant co-electrospun composite fibers were collected onto a grounded metal screen immersed in cold water. Micrometer and submicrometer cellulose fiber assemblies were obtained which were reinforced with cellulose nanocrystals and characterized by FESEM, FTIR, TGA, and XRD. Surprisingly, it was determined that the physical properties for the cellulose controls are superior to the composites; in addition, the crystallinity of the controls was slightly greater.}, number={22}, journal={LANGMUIR}, author={Esteves Magalhaes, Washington Luiz and Cao, Xiaodong and Lucia, Lucian A.}, year={2009}, month={Nov}, pages={13250–13257} }

The experimental data show that the as-prepared PPPA film exhibits a hydrophilic nanoporous structure, abundant -COOH functional groups in the polymer backbone, and high fluorescent emission under laser excitation. On the basis of these unique properties, further experiments were conducted to demonstrate three potential applications of the PPPA film in chemical and biological sensors: a permeable and permselective membrane, a membrane with specific recognition sites for biomolecule immobilization, and a fluorescent conjugated polymer for amplification of fluorescence quenching. Specifically, the permeability and permselectivity of ion species through the PPPA film are detected by means of rotating-disk-electrode voltammetry; the specific recognition sites on the film surface are confirmed with protein immobilization, and the amplification of fluorescence quenching is measured by the addition of a quenching agent with fluorescence microscopy. The results are in good agreement with our expectations.}, number={7}, journal={ACS APPLIED MATERIALS & INTERFACES}, author={Dong, Hua and Cao, Xiaodong and Li, Chang Ming}, year={2009}, month={Jul}, pages={1599–1606} }

The relevant parameters affecting the formation of nanoporous structure in the alloying/dealloying process in organic electrolyte and the post-treatment in sulfuric acid solution are investigated in detail by simultaneous electrochemical and field emission scanning electron microscopy (FESEM) characterization. Herein, a new strategy for direct estimation of the end-point in the dealloying process is developed, assuring the success of preparing nanoporous gold (NPG) films with the highest purity and porosity. Our method is especially useful for fabrication of nanoporous structure on ultrathin Au films without any further deposition of Au. The as-prepared NPG thin films are then used as anodic catalysts for borohydride oxidation in the direct borohydride fuel cell (DBFC), which show much higher catalytic activities i...}, number={2}, journal={JOURNAL OF PHYSICAL CHEMISTRY C}, author={Dong, Hua and Cao, Xiaodong}, year={2009}, month={Jan}, pages={603–609} }

The conditions were optimized to induce the grafting of part of the pre-synthesized WPU chains on the surface of cellulose nanocrystals (CNs) and the corresponding nanocomposites were processed by casting and evaporation. The morphology, structural, thermal, and mechanical properties of the resulting nanocomposite films were evaluated by scanning electron microscopy, wide-angle X-ray diffraction, differential scanning calorimetry, dynamic mechanical analysis, and tensile tests. The success of the grafting was substantiated by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and differential scanning calorimetry. Thus, it was demonstrated that the grafted WPU chains formed crystalline domains on the surface of CNs which expedited the crystallization of the polycaprolactone (PCL) soft segment domains in the WPU/CN nanocomposites. This co-crystallization phenomenon induced the formation of a co-continuous phase between the matrix and filler which significantly enhanced the interfacial adhesion and consequently contributed to an improvement in the thermal stability and mechanical strength of the nanocomposites. Although the ductility of the final nanocomposites was slightly reduced, in the CN content range from 0 to 10 wt-%, the Young's modulus and strength were significantly improved as shown by the change from 1.7 to 107.4 MPa and 4.4 to 9.7 MPa, respectively.}, number={38}, journal={JOURNAL OF MATERIALS CHEMISTRY}, author={Cao, Xiaodong and Habibi, Youssef and Lucia, Lucian A.}, year={2009}, pages={7137–7145} }
